Palm release new smart phone called Pre with GPS enabled. There is one big difference between Pre and aother GPS enabled phones, Pre has bigger screen s navigation is easier with Pre GPS then lets say G1 GPS or iPhone GPS.

TeleNav provides maps for Pre GPS maps and with internal 8 GB memory card you can load tons of maps on Pre and not to worry about running out of space.

I am not sure how long its battery will last after all Palm Pre is just a smartphone.
